Just get Company object from DB with help of Its ID. You have to maintain this ID in hidden input box inside form post and do in controller like below

@RequestMapping(value="/addLocation", method = RequestMethod.POST )
public String addLocation(@ModelAttribute("location")
Location location,BindingResult reult, Model model,@requestParam("cmpID") long ID){
    //Company companyObj=get from DB with help of ID
    //location.setCompany(companyObj);
    locationService.addLocation(location);
    return "yourview";
}
